The speed limit is now 70 mph on Wyo. Highway 120 from about 18 miles north of Cody to the Montana border.

The Wyoming Department of Transportation completed the task of changing the speed limit signs Monday.

The highway is one of three where the higher speed limit will be in place this month, if the weather permits sign installation.

The other two receiving the higher speed limit are U.S. Highway 85 north of Cheyenne and Wyo. Highway 130 from Interstate 80 south to Saratoga.

These three highway sections are among 1,546 miles of highway WyDOT identified as having the best potential for safely handling 70 mph speeds.

The decision to increase the speed limit on the three sections was made after completion of the comprehensive engineering study and traffic investigation required by state law. That study found the 70 mph limit to be safe and reasonable on those sections.

The department will monitor speeds, crashes and traffic flows on the highways, and will re-evaluate the higher limit annually.

WyDOT continues to study another 1,314 miles of highway for their potential to safely handle 70 mph speeds, including:

• U.S. Highway 14-16-20 east of Cody.

• U.S. Highway 20-26 between Casper and Shoshoni.

• U.S. Highway 287 between Lander and Rawlins.

• Wyo. Highway 220 between Casper.

• Muddy Gap and U.S. Highway 191 from Rock Springs to Pinedale.
